White color-coated steel sheets are widely utilized in construction engineering. The wavelength-distributed reflected spectral energy data of white color-coated steel sheets serves as a benchmark dataset for calculating the reflected light spectral transmittance of white color-coated steel sheet materials, and can be applied to calculate the reflected light transmittance of white color-coated steel sheet materials within any wavelength range (280–2500 nm).

1. For architectural design institutes: This dataset can be used to calculate the light intensity of reflected light in different wavelength ranges that enter buildings via surrounding white color-coated steel sheets, thereby supporting architectural optical environment design.
2. For white color-coated steel sheet component manufacturers: This data enables the calculation of light reflection levels of production components across different wavelength ranges, guiding product process optimization to reduce light environmental pollution.
3. For environmental law enforcement agencies: This dataset can be used to calculate the transmittance level of reflected light entering indoor spaces (or enclosed spaces) of subjects affected by light pollution, where the reflected light is increased by reflective materials from white color-coated steel sheets installed on surrounding buildings, to evaluate the impact degree of light pollution.

### Algorithm Rules
1. Data Source: The data is derived from tested and calibrated wavelength-by-wavelength energy distribution of the reflected spectrum of white color-coated steel sheets (tested using a spectrophotometer with a 1 nm wavelength step).
2. The reflected light transmittance $
ho(b)$ of the white color-coated steel sheet material is calculated as: $
ho(b) = frac{sum W(i) cdot
ho(i)}{sum W(i)}$. Where:
- $W(i)$ is the radiant energy of sunlight reflected by the white color-coated steel sheets at a single wavelength, and $W(i) = G(i) cdot F(i)$;
- $G(i)$ is the radiant energy of the solar spectrum at a single wavelength;
- $F(i)$ is the reflectance of the white color-coated steel sheets at each individual wavelength;
- $
ho(i)$ is the transmittance of a specific material at a given wavelength;
- $sum [W(i) cdot
ho(i)]$ represents the total reflected spectral transmittance energy of the white color-coated steel sheets in the target calculated or tested wavelength band;
- $sum W(i)$ represents the total reflected solar energy of the white color-coated steel sheets in the target calculated or tested wavelength band.
3. After testing the transmittance of arbitrary energy of the material at each wavelength, this dataset can be used to calculate the reflected light transmittance of the white color-coated steel sheet material corresponding to a specific wavelength band.
